COMBINATION VOICE-EXTENSION ATTAC I-DWENT.

Specification of Letters Patent.

Patented July 30, 1907.

A li ti fil d November 3, 1906. Serial No. 341,958.

To all whom it may concern:

Be it known that 1, JOHN N. COURTNEY, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful improvements in CombinationVoice-Extension Attachments, of which the following is a specification.7 The object of my invention is to provide a voice auxiliary or mouthattachment designed to be retained in the roof of ones mouth for thepurpose of augmenting and rendering smooth or sweet the tones of thehuman voice.

The invention consists essentially of a reed attachment designed to beheld in the roof of a persons mouth on a dental plate such as isordinarily used for holding one or more upper teeth, and in theconstructions and arrangements of the parts hereinafter specificallydescribed.

For full description of the invention and the merits thereof and also toacquire a knowledge of the details of construction, reference is to behad to the following description and accompanying drawings in which:

Figure 1 is a sectional view of my improved device showing itsapplication; Fig. 2 is an end view of the entire device detached; Fig. 3is a bottom lan view; Fig. 4 is a transverse sectional view; Figs. 5 and6 are detail perspective views respectively of the base plate and flapor cover of the device detached.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawing, the numeral 1 designates a dental plate suchas is ordinarily used to hold one or more teeth of an upper set anddesigned to be removably secured in the roof of ones mouth, and saidplate is provided in its outermost walls with a groove 2.

3 designates the base plate of my improved voice augmenting device forwhich the dental plate 1 con stitutes a support, said base plate 3 beingremovably secured to the dental plate by being inserted in the groove 2,as shown. The base plate 3 is provided with one or more slots 4 and overthese slots are pallets or reeds of gold or other metal secured at oneend and free at the other end, and arranged to produce a musical soundwhen blown through. In the present instance the slots are three innumber and are so proportioned as to produce a musical chord. Thepallets 5 are located on the upper face of the base plate 3, and on thelower face of said base plate are two studs designated and 7,respectively.

8 designates a cover plate or flap, which is provided at one edge withtwo projecting ears 9 and 10, one of said ears being provided with anelongated aperture, and the other with an end recess. The stud 6 isprovided with an angular-1y disposed extremity 6 and the stud 7 has ahead 7, as shown. The aperture of the ear 9 is so arranged that it mayaccommodate the angular extremity of the stud when the flap or coverplate 8 is disposed at right angles to the base plate 3. In thisposition the cover plate may be secured to and as readily detached fromthe base plate, but when the flap 8 is turned around so as to bring therecessed ear 10 into engagement with the headed stud 7, said cover plateor flap will be securely held to the base plate. As the side walls ofthe dental plate 1 engage with the side edges of the flap 8 when thedevice is in position, it will be seen that the cover plate or flap 8will at all times, in operation, be held securely in proper relation tothe base plate. When the base plate with the flap is removed from thedental plate 1, the said flap may be detached from the base plate byswinging it around on the stud 6, as is manifest, and the slots 4 maythen be readily cleaned if necessary.

The flap 8 is provided at its rear edge with a flange 12 which engagesthe lower face of the base plate 3 so as to hold the flap alwaysslightly spaced from the base plate, and said flap is provided with anydesired number of orifices 11, so that the air issuing through the baseplate may have free escape.

From the foregoing description in connection with the accompanyingdrawing, it is evident that when the dental plate with my attachmentsecured thereto is held in the roof of a speakers or singers mouth, thesound of the voice will be augmented and rendered sweet by the airpassing into the space 13 above the base plate and underneath the reeds5, through the slots 4 and the orifices 11.

The attachment is so arranged as to be inconspicuous, and it will becheap to manufacture and easy to assemble and will not be liable tobecome fouled or choked up with particles of food, in view of the factthat the flap 8 effectively covers the slots 4.

Whenever it is necessary to clean the attachment, this may be readilydone by simply sliding the plate 3 from its retaining groove in thedental plate 1 and then detaching the base plate in the manner abovedescribed.

Having thus described the invention, what is claimed as new is:

1. A device of the character described, comprising a dental plateadapted to be inserted in the roof of ones mouth, and a base platesupported bysaid dental plate and pro vided with one or more reeds.

2. A device of the character described, comprising an upper dentalplate, and a base plate provided with one or more reeds and dctachablyconnected to the outermost walls of said dental plate.

3. Adevicc of the character described, comprising a dental plate adaptedto be held in the roof of ones mouth, a base plate supported by saiddental plate and provided with one or more reeds on its upper face, anda flap secured to the lower face of said base plate.

4. A device of the character described. comprising an upper dentalplate. a base plate supported by said dental plate and provided with oneor more reeds on its upper face, and a flap secured to the lower face ofsaid base plate and having a detachable connection therewith.

5. A device of the character described, comprising a dental plateadapted to be held in ones mouth, a base plate supported by said dentalplate and provided with one or more reeds and slots coacting with saidreeds, and a flap secured to said base plate and providedwith a flangeholding it spaced from the base plate, the said flap being also providedwith orifices.

6. A device of the character described, comprising a dental plateadapted to be held in the roof of ones mouth, a base plate supported bysaid dental plate and provided with one or more reeds on its upper faceand studs on its lower face, and a flap adapted to be located on theouter face of said base plate and provided with one aperture and onerecessed ear arranged for detachable engagement with said studs.

7. A device of the character described, comprising an upper dental plateprovided in its uppermost walls with a groove, 21 base plate fitting insaid groove and provided on its upper face with one or more reeds, and aflap secured to the lower face of said base plate with its side edgesengaged by the walls of the dental plate.

In testimony whereof I afiix my signature in presence of two witnesses.
